I like how it detects and remove malware from my computer (which I am very satisfied of). When scanning, some files will need to open first before they are detected. This creates an extra step but not much as everything seems ok. There's nothing really wrong with this software. As long as you have enough RAM you should be fine. You won't regret installing this software if you use multiple tabs at once during browsing. If you only want one software installed then I suggest looking into ESET antivirus (it does pretty much the same thing). Malware detection/removal.
